IQM Academy – Challenges Ahead

Challenges Ahead In Quantum Computing

Prepare the qubit below in the \(\ket{1}\) state by applying an X gate and wait.

What best describes your observation?

A

Nothing
B

The state of the qubit drifts towards the \(\ket{0}\) state
C

3
D

5

Exactly! This illustrates the speed up gained even more. In general, instead of \(n\) guesses we needed classically to obtain a \(n\)-digit secret code, we just need one, no matter how many digits the secret code has.
